Department of Health figures published last month showed Birmingham Heartlands and Solihull NHS Trust had the seventh worst rate of MRSA infection among general acute hospitals in England over the past three years.
In general, the prevalence of TB infection in badgers was higher in the northern group of counties involved (Gloucestershire, Herefordshire, Shropshire and Worcestershire) than those in the southern group (Cornwall, Devon and Dorset), the survey concluded.
But it said evidence revealed the general UK population was not at increased risk of TB, HIV or malaria infection from migrants, but some UK-born ethnic communities did have a higher risk of disease because of their links to countries where the diseases were endemic.
